Blade Installation
Refer to Figure 11.
CAUTION
Your dealer can supply genuine replacement blades. Substitute
blades may not meet original equipment specifications and may be dan-
gerous.
NOTICE
Crossbar rotation is counterclockwise when looking down on cut-
ter. Be sure to install blade cutting edge to lead in counterclockwise rota-
tion.
Always replace or sharpen both blades at the same time.
1.
Inspect blade pin (1) for nicks or gouges, and if you find any replace the
blade pin.
2.
Insert blade pin through the blade. Blade should swivel on blade pin; if it
doesn't determine the cause and correct.
3.
Align crossbar assembly (3) with blade access hole in cutter frame. Apply
a liberal coating of Never Seez
hole. Make sure blade offset is away from cutter.
4.
Insert blade pin (1) through blade. Push blade pin through crossbar.
5.
Install shims (4 & 5) over blade pin.
NOTE: Only use enough shims to allow keyhole plate (6) to slide into
blade pin groove.
6.
Install blade clip (7) over keyhole plate and into blade pin groove.
7.
Secure into position with cap screw (8). Torque cap screw to 115 N-m (85
lbs-ft.).
8.
Repeat steps for opposite side.
NOTE:
Blade should be snug but should swivel on pin without having
to exert excessive force. Keep any spacers not used in the installation as
replacements or for future installation.
Blade Sharpening
NOTICE
When sharpening blades, grind the same amount on each blade
to maintain balance. Replace blades in pairs. Unbalanced blades will
cause excessive vibration, which can damage gearbox bearings. Vibra-
tion may also cause structural cracks to cutter.
1.
Sharpen both blades at the same time to maintain balance. Follow
original sharpening pattern.

2.
Do not sharpen blade to a razor edge—leave at least a 1.6 mm (1/16")
blunt edge.
3.
Do not sharpen back side of blade.

SLIP CLUTCH ADJUSTMENT
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected if the cutter strikes an obstruction.
A new slip clutch or one that has been in storage over the winter may seize.
Before operating the cutter, make sure it will slip by performing the following
operation:
1.
Turn off tractor engine and remove key.
2.
Remove driveline from tractor PTO.
3.
Loosen six 10 mm cap screws (6) to remove all tension from Belleville
spring plate (5).
4.
Hold clutch hub (3) solid and turn shaft to make sure clutch slips.
5.
If clutch does not slip freely, disassemble and clean the thrust plate faces
(4), flange yoke (1), and clutch hub (3).
6.
Reassemble clutch.
7.
Tighten Belleville spring (5) until it is against the thrust plate (4) of the
clutch, and then back off each of the six nuts by 2 full revolutions. The
gap between Belleville spring and thrust plate should be 3.2 mm (1/8") as
shown in Figure 13.
8.
If a clutch continues to slip when the spring is compressed to 3.2 mm
(1/8") cap, check friction discs (2) for excessive wear. Discs are 3.2 mm
(1/8") when new. Replace discs after 1.6 mm (1/16") wear. Minimum disc
thickness is 1.6 mm (1/16").
